SPECIFICATION forming part of Letters Patent No. 754,625, dated March15, 1904.

Application filed April 24, 1903. Serial No. 154,053. (No model.)

To all" whom, it may concern:

Be it known that I, J USTUS A. TRAUT, a citizen of the United States,residing at New Britain, Hartford county, Connecticut, have inventedcertain new and useful Improvements The purpose of the invention is toprovide a carrier which may be adjusted to saw-blades.

of different thicknesses without twisting said blades.

In the drawings, Figure 1 is a side elevation of my invention. Fig. 2 isa sectional View on the plane of the line 2 2, Fig. 1, solid linesindicating one adjustment, the dotted lines indicating anotheradjustment. Fig. 3 is a side elevation of a'modified construction. Fig.4 is a front elevation of the construction shown in Fig. 3.

I have shown only such parts as are necessary to a full understanding ofmy invention.

The saw-carrier comprises two sections 1 1. These sections are pivotallymounted upon cylindrical posts 2 2, which constitute the guide proper.The carrier holds the saw, and the space between the two halves 1 1,which receives the saw-blade, is preferably enlarged at the upper end,as at 3, to receive the sawback. In Fig. l I have shown the sections 1 1as of semicylindrical form; but later it will be shown that the shape isnot essential. As before indicated, these sections 1 1 are spaced apartto form the passage for the blade of the saw. This is seen in both Figs.1 and 2. Since saws vary in thickness and since it is essential to finework that the carrier fit fairly close to the saw-blade to properlysteady the same in use, I have so constructed the parts that thispassage may be readily adjusted as to width to receive saws of varyingthick-.

nesses. v

The cylindrical guide-posts 2 2 are mounted in a base 4:, Figs. 3 and 4,and this base 4 has a stud-like bearing 5, which may be fitted in of amiter-box. base 1 to be rotatably adjusted on said swingingsupporting-arm. This rotatable adjustthe customary way to the usualswinging arm This connection permits the ment is utilized in effectingthe adjustment of the sections 1 1 as to their distance from each other.For example, referring to Fig. 2, the

dotted lines indicate theposition of the sections 1 1, as shown inFig. 1. -The solid lines show the position of the parts when anadjustment has been effected to vary the space through which thesaw-blade passes. This variation in adjustment .is effected by rotatingthe base 4.

6 represents a portion of a saw-blade of a 4 thickness adapted to fitthe space between the parts shown in solid lines, Fig. 2. Obviously, ifthe line of the saw-blade 6 is preserved and the supporting-base of thesaw-carrier is ro tated to the right it will shift the two sections fromthe position indicated in solid lines to the position shown in dottedlines and widen these points are spaced apart on opposite sides of theguide-posts 2. These points are indicated at 7 8 and 9 10. Thecarrier-sections 1 1 being free to turn or rock on the post 2 2 andthere being a set of saw-bearings on each side of the guide-posts 2 2 itis possible to .adjustthe carrier-sections to exactly the right spagingwithout twisting or buckling the sawb a e.

Substantially an equivalent construction is shown in the modificationFigs. 3 and 1, in which instead of providing two separate sets ofbearings on opposite sides of the posts a long bearing is provided foreach side of the saw-blade, each of said bearings extending on each sideof the guide-posts. In the modification the saw-sections 11 11 arepivotally mounted or swiveled on the cylindrical guides 2 2 in a mannersimilar to the sections 1 1. (Shown in Figs. 1 and 2.) These plate-likecarrier-sections are spaced apart to afford a passage for the saw andthe saw-back, and in operation they may be adjusted in a manner similarto the sections 1 1.

\Vhat I claim is 1. In a miter-box, an adjustable saw carrier and guide,the same comprising a pair of posts spaced apart and parallel with eachother and a rotatable support therefor in common to both, a pair ofsections to carry the saw, each of said sections being swiveled uponsaid posts whereby by rotating said support said sections may beswiveled thereon and the space between them through which the saw-bladepasses varied, said sections having a saw-engagingrange greater thantheir angular movement with said posts.

2. In a miter-box, an adjustable saw carrier and guide the samecomprising a pair of posts spaced apart and parallel with each other,and a rotatable support therefor in common to both, a pair of sectionsto carry the saw, each of said sections being slidably mounted andswiveled on said posts whereby by rotating said support said sectionsmay be swiveled thereon, and the space between them through which thesaw-blade passes varied, said sections having a saw-engaging rangegreater than their angular movement with said posts.

3. In a miter-box, an adjustable saw carrier and guide, the samecomprising a pair of cylindrical posts spaced apart and parallel witheach other and a rotatable support therefor in common to both, a pair ofsections to carry the saw each of said sections extending on each sideof said posts to afford a broad bearing for a saw-blade, each of saidsections being swiveled relatively to the axis of said posts whereby byrotating the support said sections may be swiveled and the space betweenthem through which the saw-blade passes varied.

4. In a miter-box, a combined adjustable saw guide and carriercomprising a pair of cylindrical posts spaced apartand parallel witheach other, a rotatable support therefor in common to both, a pair ofsections each of said sections being of segmental form and arranged withtheir fiat sides facing each other and each of said sections beingswiveled upon said posts whereby by rotating said support the adjacentfaces of said sections may be moved toward or away from each other.
